Each culture has its own halvah, united only by nameâwhich derives from the Arabic word for âsweetââand the fact that each is a sweetened candy or dessert, often an ancient and beloved recipe. A trip to Israel is not complete without sampling the countryâs halvah.
The amount of vitamin D you get from exposing your bare skin to the sun depends on: 1  The time of day â your skin produces more vitamin D if you expose it during the middle of the day. 2  Where you live â the closer to the equator you live, the easier it is for you to produce vitamin D from sunlight all year round.
Vitamin D is found in many foods, including fish, eggs, fortified milk, and cod liver oil. The sun also adds to the body's daily production of vitamin D, and as little as 10 minutes of exposure is thought to prevent deficiency. The term vitamin D refers to several different forms of this vitamin. Two forms are important in humans: vitamin D2, which is made by plants, and vitamin D3, which is made by human skin when exposed to sunlight. Foods may be fortified with vitamin D2 or D3.
